Abstract
A calibration apparatus for determining a location of a transponder supported by a printer media. The calibration apparatus uses a transceiver to attempt to read, write or otherwise communicate with the transponder. Controller logic of the calibration apparatus uses successful and unsuccessful attempts to communicate to determine the location of the transponder. For example, the controller may be configured to move the media in increments, each of the increments associated with a successful or unsuccessful attempt to communicate with the transponder. The successful attempts, and their relative media positions, are correlated with the position of the transponder. Also, the controller may be configured to use different power levels for the transceiver and its one or more couplers to determine which power levels are required to successfully communicate with the transponder. These power levels are correlated with characteristics of the performance of the transponder to determine its distance from the antenna/coupler.
